Through the related technical information of the monitoring of bridge construction, this is to determine BP neural network's input and output parameters, to establish the neural network fore-casted model, and to carry through the prediction to the main beam of deflection. In the application, the data of deflection deviation has generated through the cast-in-place segmental cantilever to train the BP neural network. The deviations which are produced in the pre-run neural networks predict the follow-up segment in construction, and then simulation control in the cable-stayed bridge is realized in construction process.

Under the influence of COVID-19, the economic benefits of shale gas development are greatly affected. With the large-scale development and utilization of shale gas in China, it is increasingly important to assess the economic impact of shale gas development. Therefore, this paper proposes a method for predicting the production of shale gas reservoirs, and uses back propagation (BP) neural network to nonlinearly fit reservoir reconstruction data to obtain shale gas well production forecasting models. Experiments show that compared with the traditional BP neural network, the proposed method can effectively improve the accuracy and stability of the prediction. There is a nonlinear correlation between reservoir reconstruction data and gas well production, which does not apply to traditional linear prediction methods
